I just bought the 1400 and there was so many reviews saying it sounded great and the bass was awesome, got them today, been playing with them all afternoon and to be honest, even though I have onboard sound, it's one of Realtek's best and has headphone amplifiers built in, it wasn't until i installed the razer surround program that the headset finally shined and sounded amazing in BF3, sucks that I don't have pro so I can't calibrate it like you would, but right now im loving these with the surround on, it just explodes, so dont know if you're into bass but these are a tad bit high on bass and lacking on the mids and highs...if it wasn't for the fact that I bought them on sale on newegg for $52.99 - 10% coupon = $47.63 so I did get a gread deal because of course these aren't seinheiser but after using my $15 in newegg credits and costing me out the door $33 i cannot complain for the quality plus they are comfy as well, I know it doesn't help but I would tell you NOT to get the HS30 simply because that is considered a lesser quality headset than the Vengeance line by Corsair themselves..if you look at youtube videos even though these came out after the vengeance they are marketed, and priced, as lower quality levels. My other choice was the Logitech G230, but in the end the reviews of the boominess of the 1400 is what swayed me to it. Ill never know what the G230's will sound like...
EDIT: after some breaking in these are sounding better when listening to music when Im NOT using razer's surround, they sound awesome by themselves for music, gaming i enable razer's surround
EDIT OF EDIT: lol sorry but in live songs, it sounds better with surround on, so it depends on the tune i guess!
